By default, all software supports multiple file extensions. XMLSpy supports at least 11 different file extensions. The basic files that XMLSpy supports are .JSON. However, not all of the extensions listed on the list are always used to save the effects of work in XMLSpy. Very often, files with such extensions are used as source data files used by XMLSpy.
XMLSpy can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via XMLSpy and try to save it in another file format, also supported by XMLSpy.
